In times of the Anthropocene and extreme political and economic injustice, recognizing the power of our voice to flourish or destroy worlds has drawn our attention to our sound and breathing organ, the vocal cord, hidden inside the Larynx. Speaking truth to power and confronting injustice with our voices has been transformative ever since. By exposing the human larynx as a biological instrument hidden inside the human body, we can understand how much we are materially rooted and how our feelings and thoughts have a material dimension. Reconnecting to our material significance could reduce alienation, separation, and the gap between nature and culture. Moreover, the porcelain sculptures series produces a sound composition focusing on the ethics of confronting abuse and violence, borrowing from the 'nonviolence' movements and the method of 'calling-in.'
